LIQUID METER.

Application filed November 17, 1919.

T 0 all to how it may concern Be it knownthat we, PATRICK J. ROAOH andDANIEL CARTER, British subjects, residing at the city of Toronto, in thecounty of York and Province of Ontario, Dominion of Canada, haveinvented certain new and useful Improvements in LiquidMeters; and wehereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to a liquid meter comprising two correspondingmeasuring receptacles, each having an outlet port, alternately openedand closed by a float-moved valve connected with and actuating a rockerbeam controlled by a float operated escapement lock, and an inlet portalternately opened and closed by the action of the beam.

In carrying out the invention'the outlet ports are arranged at thebottom of the receptacles and preferably discharge into an outletmanifold, and their valves are hinged to the lower ends of apair ofconnecting rods, the upper ends of which are hinged to the rocker beamon opposite sides of its fulcrum, the floats actuating these valvesbeing fixed on the connecting rods near their lower ends.

Above the receptacles is an inlet manifold having an inlet port for eachreceptacle alternately opened and closed by a valve having a rackmeshing with a segmental gear mounted on a spindle actuated by therocker beam, and provided with an arm having at its free end a pin orroller.

Above each receptacle is a float chamber, having a perforated bottomthrough which the liquid content of the receptacle can enter it, andwithin each float chamber is a float bearing against or looselyconnected with the long arm of an escapement lever, the

short arms of these levers overlapping each other and underlying thepath of the pin or roller and forming with it an escapement lock for therocker beam.

\Vithin the meter, above the inlet valve and its operating gear, is abaflie to prevent access to the internal mechanism of the meter, andabove the baffle is a screen to break the force of the inflowing liquid.

For an understanding of the invention reference is to be had to thefollowing description and the accompanying drawings in which:

The meter consists of a tank a, divided by a vertical'partition 6 intotwo corresponding measuring receptacles c, c, constructed to hold anypredetermined quantity of liquid. At the bottom of the tank is' anoutlet manifold (Z having an outlet port cl for the measuring receptacle0, and an outlet port d for the measuring receptacle 0, and at the sidesof the outlet ports d, d, are vertical guide'rodse, extending above theinanifold. The outlet ports d, d, are provided with outlet valves f, f,having guideways g embracing the guide rods 6 for the move ment of thevalves in a fixed path when re spectively opening and closing the outletports. *ach of the outlet valves f, f, is provided with lugs 7t, andcontained between the lugs of each of the outlet valves, is the lowerend of its respective connecting rod i, z". Passing through the lugs h,and connecting rods 2', 2", are pin s by which the connecting rods andvalves are hinged together. Fixed on the connecting rods 2', 2', neartheir'lower ends are floats la, la, respectively, these floats beingheld in position by washers Z, the floats as shown in Fig. 1 being sopositioned on the connecting rods as to clear the top of the guide rods6, when the outlet valves are lowered to close the outlet ports. At thetop of the measuring receptacles 0, 0, is a lid or cover m, againstwhich abuts the top of the vertical partition I) to separate themeasuring receptacle 0 from the measuring receptacle 0, and prevent anoverflow from one receptacle into the other. Formed through the lid orcover m on opposite sides of the vertical partition I), are inlet ports0, 0, for the measuring receptacles c, 0, respectively, and above thelid or cover m is an inlet manifold p, having an inlet nipple q, towhich may be connected the duct for the inflowing liquid. Within theinlet manifold p, is a slide valve r for the inlet ports 0, 0, andsecured to or forming part of the slide valve 1" is a rack r, with whichmeshes a segmental gear .9 fixed on a spindle s, j ournalled in thesides of the inlet manifold 29.

Within the inlet manifold 19 is a substantially V-shaped baffle acovering the segmental gear 8 and rack r, the apex of the baffle beingopposed to the nipple and its ides taking an inclination which willdirect the liquid to the inlet ports 0, 0, this baffle being intended toprevent access through the nipple g to the internal mechanism of theapparatus. The spindle 8' projects beyond both sides of the inletmanifold p and mounted on its projecting ends are corresponding rockerlevers or beams a, the ends of which project evenly beyond the inletmanifold. Journalled in the projecting ends of the rocker levers orbeams 14 are rock shafts o, o, and extending through these rock shaftsare the upper ends of the connecting rods 2' 5, these rods being securedto the rock shafts by means of set screws to.

By means of the rock shafts o, o, and the pivot pins j, the outletvalves 7, f, can move vertically in a fixed path on the guide rods 6,and the connecting rods 2', 2 can swing laterally when following thecurved path taken by the rock shafts o, 01, during the movement of therocker beam u. The lid or cover m is formed with QlOIL 'ZLLBCl slots 00,m, for the lateral movement of the connecting rods 2', c", andencircling the connecting rods and engaging the top surface of the lidor cover are apertured washers y, y, having a sliding movement to coverthe slots 0:, as, when the valves f, f, are lowered to prevent theliquid contents of the receptacles passing through the slots to theupper surface of the lid or cover, and uncovering the slots a2, a, whenthe valves are raised, so that any liquid that. may have passed to thetop surface of the lid or cover can drain back into the receptacles.

On the outer side of the inlet manifold is a bracket at, having two lugsa, a arranged on opposite sides of an imaginary line passing verticallythrough the axis of the spindle s. Fulcrumed to the lug a is the boss 6of an escapement lever comprising a locking arm Z) extending from thecss b in the direction of the lug a and a lif ing arm 7%", extendingfrom the boss Z) in the opposite dilection and taking an upwardlyinclined direction. Fulcrumed to the lug a is the boss 0 of anescapement lever, comprising a locking arm 0, extending from the boss 6in the direction of the lug a", and lifting arm 6 extending from theboss 6 in the opposite direction, the lift ing arm 6 also taking anupwardly inclined direction.

The escapement lever comprising the boss 6, locking arm 6 and liftingarm 6 corresponds in all particulars with the escapement levercomprising the boss 6, locking arm 0 and lifting arm 6 and whenassembled the loclring arms 5, c, overlap. The lifting arms 6 6 are eachheavier than their respective locking arms 5, e, to tilt the lockingarms .7), e, upwardly when the measuring receptacles c, 0, are empty andtheir corresponding valves 7", f, are lowered.

Fixed on the spindle s is an arm 7 having at its free end a pin orroller f to alter nately engage with the free ends of the locking arms5, e, as the arm f swings with the oscillation of the spindle 8, duringthe r cking of the lever or beam to. On the top of the lid or cover mare two float chambers g, 9, above the measuring receptacles c, 0,respectively, and within the float chambers g, g, are floats j, j.

For the movement of the lifting arms the float chambers g, g, areslotted vertically as shown at. Z, these slots serving as guideways toprevent the lateral movement of the lifting arms during the rocking ofthe escapement levers.

The free ends of the lifting arms 6 6 are bifurcated as shown at m, andthe escapement floats are provided with upwardly extending stems or pinsm, which pass between the forks of the bifurcations. The stems or pins mare screw threaded as shown in Fig. l, and are provided with groovednuts m the forks of the bifurcations at engaging in the grooves of thenuts. This arrangement insures a positive up and down movement for thefree ends of the lifting levers unitedly with the floats j, j, andprovides for the curved movement of the lifting arms when the escapementlevers are rocking on their fulcrums.

Formed through the bottom of the float chambers are apertures m topermit of the liquid within the receptacles 0, c, entering the bottom ofthe float chambers when the receptacles are full.

W hen the receptacle 0 is filled the liquid enters the float chamber gand lifts the float j into the position shown in Fig. 1. This upwardmovement of the float j raises the free end of the lifting arm 6 androcks the escapement lever comprising the boss 5 and locking and liftingarms 6', 5 on its fulcrum to lower the free end of the locking arm Z)below the path of the pin or roller P, so that the arm f can then swingin the direction indicated by arrow in Fig. l, and cause a correspondingoscillation of the spindle s and segmental gear 8 for the movement ofthe slide valve 1" to close the inlet port 0 and open the inlet port 0.This oscillation of the arm 7 brings the pin or roller into contact withthe top of the locking arm 5', which it then holds in its loweredposition to maintain the lifting arm Z7 and float j in their raisedposition, the oscillation of the arm carrying the pin or roller f beyondthe free end of the locking arm 6, which then rises and engages it tohold the arm 7 and itsrelated parts against reverse movement until thefloat j has been lifted to actuate the escapement lever consisting ofthe boss 6 lockin arm 6". and lifting arm 6 When the pin or roller f isreleased from engagement with the end of the locking arm I) and startsits movement in the direction indicated by arrow in Fig. 1, the floatmoves upwardly into the position shown in Fig. 1, and simultaneouslylifts the valve f to open the outlet port cl, and the connecting rod 1'to raise the corresponding end of the rocker lever or beam to, theactuation of the rocker lever or beam at oscillating the spindle s andsegmental gear 8, to reciprocate the slide valve 7' to close the inletport 0 ofthe measuring rece'ptacle 0 and open the inlet port 0 of themeasuring receptacle 0. The liquid can then flow through the nipple q,inlet manifold p and inlet port 0 to the receptacle 0.

When the liquid is flowing into the measuring receptacle 0 the pinorroller f remains in engagement with the end of the locking arm'e"until the liquid in the measuring receptacle 0 rises to a height toenter the float chamber g" andlift the float j" sufliciently to lowerthe locking arm '6 and release the pin or roller for the oscillation ofthe arm 7 in the opposite direction, the lever f? their carrying theroller f past the end of the locking arm Z), which rises and holds thearm 7 and related parts against reverse movement, the roller f thenengag ing, the top surface of the locking arm 6" and holding it loweredto maintain the lifting arm 6? and float j in their elevated position.The float k is then free to rise and lift the outlet valve 7" to openthe outlet port r for the liquid within the measuring receptacle 0 toflow out through the outlet manifold, The upward movement of the float kraises the corresponding end of the rocker lever or beam at, causingitto roclc the spindle s and actuate the segmental gear to move theslide valve r to cover the inlet port 0 and uncover the inlet port 0;This movement of the rocker lever or beam it lowers the float 7c andvalve f until the outlet port 03 is closed. When the pin or roller fpasses beyond the end of the locking arm I), the float j can descend bygravity, and lower the free end of the lifting arm 6 and raise the freeend of the locking armb to engage the pin or roller f and hold itagainst movement until the float j has again been lifted by the liquidwithin the measuring receptacle 0. This action of the parts is repeatedalternately with respect to the measuring chambers'c, 0, while theliquid 1" represents a train of registering wheels operated by therocking movement of the lever or beam a, which is provided with twooffsets r on opposite sides ofthe spindle s, engaging with pins 8 on theregistering wheels 3. 7
